Garbage! hangs up and the slide cuts into the barrel - L2D Combat Precision Match Fluted Barrel, Smith & Wesson M&P Shield 9

Bought the non threaded bronze fluted barrell for my m and p shiel.Price isn't cheap either. I decided to buy directly from L2D. After getting the run around from L2D Combat on my address, they finally shipped the barrel. Went to the range for the first time about a week ago and immediately started having issues with the gun not firing.The barrel is not even sized correctly. So much to the point the slide has cut into the barrel past the bronze coating and I can see shiny silver which I'm sure will rust at some point. This product is complete garbage. Lesson learned and a $200 waste of money!!!!
